摘要
采用单轴拉伸扫描电镜动态观察技术,对铝铜合金过时效多晶体变形中的剪切带形成和扩展全过程进行了观察,并分析讨论了材料组织对剪切带形成和扩展的影响.
All Process of formation and development of shear band was studied by adopting in-site tensile dynamic SEM observation in overaged aluminum-2. 45wt% Copper alloy polycrystal. Further, the effect of mi-crostructure on formation and development of shear band was analysed on above observation basis.
